Plastics: Discovered by accident.
Plastic was actually discovered by a famous German chemist Christian Schonbein in 1846. Plastics were actually discovered accidentally. Christian was experimenting in his kitchen and by accident he spilt a mixture of nitric acid and sulphuric acid. To mop that solution i.e.. mixture of nitric and sulphuric acid he took a cloth and after moping he kept it over the stove. After sometime, the cloth disappeared and that was the beginning of Plastics.
